The error corresponding to the range leads to the PLC calculation error. For the range, please refer to the technical indicators in the first part.2. The wiring method is incorrect or the wiring sequence is wrong.3. The power supply voltage is wrong (for the 0-10V type, the power supply is 24V).4. The distance between the transmitter and the collector is too long, causing signal disorder.5. The PLC acquisition port is damaged.6. The equipment is damaged. 0%RH~95%RH (non condensing) -40~+120, default -40~+80
